SPECIFICATION forming part of Letters Patent No. 766,826, dated August 9, 1904.

Application filed April 4, 1904. Serial No. 201,532. (No model.)

invented certain new and useful Improvements in a Combined Dishing and Flanging Machine, of which the following' is a specification,

This invention relates to improvements in a machine to be used for dishing and flanging by a rolling operation fiat circular disks or plates such as are used for boiler-heads, tanks, and the like; and it consists in certain peculiarities of the construction, novel arrangement, combination, and operation of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed.

The principal object of the invention is to provide a machine of the above-named character which shall be strong, durable, and comparatively simple and inexpensive in construction and so made that its parts maybe adjusted in such a manner as to readily admit of the insertion and the withdrawal of the plates or disks to be operated upon.

Another object of the inventio'ii is to provide a machine by means of which the disks may be dished by one operation and flanged by another or dished and hanged at the same time by a single operation.

A further object is to provide a Hanging and dishing machine the parts of which may be so adjusted that plates or disks of various dimensions can be treated by the same machine to produce iianged or unflanged heads of the desired convexity and for boilers or tanks of different sizes.

Still another object of the invention is to provide means whereby in the operation of forming the flanges on the disks the same will be strengthened at the bend thereof rather than weakened.

Other objects and advantages will be disclosed in the subjoined description and explanation.

In order to enable others skilled in the art to which my invention pertains to make and use the same, I will now proceed to describe it, referring to the accompanying' drawings, in which- Figure l is a side View in elevation of a com bined Hanging and dishing machine embodying my invention, showing' the parts in operative positions for dishing and flanging a disk and illustrating the disk in section.

Fig. 2 1 is a cross-section thereof, taken on line 21 2l of Fig. 20; and Fig. 22 is a side or face view of the rollerbearing bracketwhich said mechanism carries, showing the roller removed.

Like numerals of reference refer to corresponding parts throughoutthe different views of the drawings.

The base or foundation 30, upon which the machine rests, may be made of any suitable size, form, and material, but is herein shown as comprising a number of pillars 31, 32, 33, and 34, suitably spaced to support the different parts of the machine, as will be hereinafter set forth. Horizontally mounted on the base 30 is a bed-plate 35, which is provided on its upper surface with a series of grooves 36 to receive projections or tongues 37 on the lower surface of a sliding plate 38, which, like the bed-plate 35, is substantially rectangular in shape and has at each of its rear corners an extension 39 to rest on the pillars 33 and 34 of the foundation and to support a portion of the frame of the dishing mechanism. rl`he central rear portion of the sliding plate 38 is provided with a longitudinal recess 40 to permit of the movement of the support 4l for the front portion of the Hanging-mechanism-carryingv frame, which'support is adjustably secured to the foundation by means of bolts 42 or otherwise. Eachside of the bed-plate 35 is provided near its front end with a rack 43, with which engage pinions 44, mounted on the lower ends of shafts 45, which are'vertically journaled on brackets 46, carried by the sliding' plate 38, as is clearly shown in Figs. l and 2 of the drawings. Each of the shafts 45 is provided at its upper end with a h and-wheel 47, used for turning them, so that the sliding plate may be reciprocated on the bed-plate. Mounted on the upper surface of the sliding plate 38 near each of its front corners is a standard 48, which has in its upper end a screw-threaded socket. Vertically located in each of the sockets of each ofthe standards 48 isa screwthreaded adjusting-rod 49, which is provided at its upper end with a hand-wheel 50, used for turning the same in raising and lowering or adjusting the upper frame, which carries a part of the dishing mechanism. This upper frame comprises'side rails 5l and a front end rail 52, which are preferably made of channel-iron, as shown, and are united to form three sides of a rectangular figure, the rear portion being left open. Asis clearly shown in Figs. l and 2, the adjusting-rods 49 are vertically journaled in or near the front corners ofv said frame. The rear ends of the rails 5l are ldownturned and pivotally secured on the upper ends of standards 53, which extend upwardly a suitable distance and are supported on the extensions 39 of the sliding plate. Extending across the said upper frame and united to the said rails 5l thereof are beams 54, which are preferably in pairs and are located parallel with one another at a slight distance apart and near the middle of said frame.

Pivotally secured at their inner ends to suitable brackets on the front portion of the lower front cross-beam 54 near its middle are two segmental gears 56, which are radially arranged With respect to the center of the disk, as will be presently explained. The toothed end of each of the gears 56 extends to near the rear surface of the front rail 52, which carries downwardly-projecting curved guides 57, which are arranged in pairs, so that one of the segmental gears will operate between the members of one pair and the other gear between the members of the other pair, which serve to prevent lateral movement or displacement of the gears. Transversely journaled on the Lipper surface of the rail 52 is a shaft 58, on which are mounted two pinions 59 to mesh with the teeth of the segmental gears 56, and thereby raise and lower the same, which may be done by turning the shaft 58 by means of a hand-wheel 60, mounted thereon. As is clearly shown in Figs. 3, 5, and 8, each of the curved extensions or arms 6l of the gears 56, the inner end of which is pivoted, as before stated, to the lower front cross-beam 54, is provided with a longitudinal slot 62 for the reception and operation of the bearings and stems therefor of a series of rollers used in the operation of dishingthe disk. The lower portion of each of the segmental gears is provided with a screw-threaded opening 63 to receive an adjusting-screw 64, each of which has on its end a hand-wheel 65 used for turning' the sanie.

Located in each of the slots 62 of the arms 6l of the segmental gears are a number of sleeves 66, having portions 67, angular in crosssection, to rest in said slots. Each of, the angular portions of each of the sleeves is provided on opposite sides with laterally-extending apertured lugs 68, and said sleeves are connected together by means of links 69, which have forked and apertured ends to receive the ends of the lugs 68 and suitable pivot-pins. Passing through an angular opening in each of the sleeves 66 is an angular stem 7(),which has a roller 7l journaled on its lower portion. Located on the upper portion of the stem 70, so as to rest on the upper surface of the arm 61 of the segmental gear, is a cap 72, which is held in place by means of nuts 73, engaging screw-threads on the upper end of the rollerstem 70, as is clearly seen in Figs. 3, 7, andl 10 of the drawings. The inner end of each of the screws 64 is connected to the sleeve 66 adjacent thereto by means of a swivel, so thatby IOO IIO

turning the screw in the proper direction the series of rollers carried by each of thearms of the segmental gears will be moved back and forth, so that the proper adjustment thereof may be attained to give the desired convexity to the disk or plate 74 when the same is being dished. As before stated, the crossbeams 54 are located in pairs and a slight distance apart, as is clearly shown in Figs. 3 and 5, and have located therebetween at about their middle a rectangular casing 75, which is held in place by means of iianged plates 76 and 77, bolted to said casing and the crossbeams. Fitted in the casing 75 is a shaft 78, on the lower portion of which is journaled a beveled gear 79, which is preferably made of two pieces secured together by means of bolts 80, which is best shown in Fig. 1 of the drawings, rl`he lower end of the shaft 78 is pro vided with a socket 81, in which is fitted a stub-shaft 82 on the upper surface of a revolvingdisk 83, which has interposed between it and the lower surface of the shaft 78 a series of antifriction-balls 84 to provide a ballbearing in said disk. This disk is rotatably secured on the shaft 78 by means of semicircular pieces 85, which surround the lower portion of the shaft and engage a groove in cross-beams 54 and carries ony its outer portion an arm 89, in each of which arms is horizontally journaled a screw-threaded shaft or worm 90. Horizontally journaled on and about the middle of the front rail 52 is a screw-threaded shaft or worm 91, which, as well as the shafts 90, has on its outer end a hand-wheel 92 for turning the same. By reference to Figs. 1, 3, and 5 of the drawings it will be seen that the shafts 90 and 91 are radially arranged with respect to the beveled gear 79 and that each of said shafts carries on its inner end a beveled pinion 93 to mesh with said gear. Loosely mounted on the screwthreaded portions. of each of the shafts 90 and 91 is a downwardly-projecting detent or foot 94, the openings inwhich to receive the shafts are screw-threaded, so that when the shafts are turned said detents will travel back andA forth thereon.

`vertically mounted A on the Vupper surface of the sliding plate 38 and radiating from a central point near the inner end of the recess 40 in' said plate are a series of braces 95, which are arranged in pairs, as is clearly shown in Fig. 6, of the drawings, and have their upper edges curved. Each of these brace-plates is provided with two or more series of openings 96 and 97, the former of which are vertically arranged, and the latter are arranged in i`nclined rows, as is clearly shown in Figs. 1 and. 3 of the drawings, and said openings are for the reception of bolts 98, which pass through openings in the shanks 99 of hangers 100, on each of which is journaled a roller 101 to'support the lower surface of the disk or plate 74 and to coperate with the rollers 71 in the operation of dishing the disk. By arranging the openings 96 in the brace-plates 95 vertically and the-openings 97 therein in inclined rows it is apparent that the Shanks 99 of the brackets or hangers 100 for the rollers 101 may be adjusted so as to give the proper conveXity to the disk 74 when it is being dished. Mounted on the upper surface of the brace-plates 95 at their adjacent ends is a table 102, which has on itslower surface a series of downwardly-extending lugs 103, which project between the inner ends of the plates 95 and are bolted thereto. This table has in its upper surface an annular groove 104, in which are radially journaled a series of rollers 105, which are movably located in said groove, so that when it is desired to fiange the disk 74 without dishing it rollers with a horizontal surface may be substituted for the rollers 105, which have inclined surfaces, as shown in Figs. 3 and 6, to permit of the disk bei-ng properly dished. The upper surface of the table 102 is provided with a central socket 106, in which is journaled the stub-shaft 107 of a rotatable disk or plate 108, between the lower surface of which and the table 12 are interposed antifriction-balls 109 to furnish ball-bearings therefor. The disk 108 serves to rotatably support the disk or -plate 74 at its center, and is clamped or pressed on its upper surface at said point by the rotatable disk 83, as is clearly shown inIFigs. 1,

2, 3, and 7 of the drawings.

The frame for the fiange and driving mech-V anism lcomprises a base 110, from the front end of which extends forwardly-projecting` arnms 111, which are pivotally secured to the upper end ofthe standard 41, which, as before stated, is adjustably mounted on the foundation, so that it can be moved back and forth IOC IIO

thereon within the recesses 40 of the sliding and bed plates.

any preferred construction and is located on` the base 110 between the uprights 116, as is Each of the arms 111 is pro,- vided with an opening 112, ineach of which" LIS clearly shown in Fig. 3 of the drawing's. Journaled on the yoke 1 18, so as to extend longitudinally with the frame, is a shaft 121, on the front end of which is detachably mounted a beveled wheel 122, which may be removed and replaced by another wheel having a greater or less degree of bevel, as may berrequired to give the proper angle to the flange 123 being formed on the plate or disk. l On the rear end of the shaft 121 is mounted a gear 124, which normally meshes with a gear 125 on the main or driving shaft 126, which is longitudinally journaled on the upper portion of the frame and has mounted on its front end a wheel 127, which impinges the upper surface of the disk or plate 74, which will be caused to rotate by means of the revolution of the wheels 122 and 127 as is apparent. The shaft 121 may be raised and lowered by means of the compressor 120, so that the disk 74 may be inserted between the wheels 122 and 127 or so that the pressure of the former wheel may be regulated so as to clamp the disk between it and the wheel 27 sufiiciently to cause it to rotate by reason of the frictional contact of said wheels. Mounted on the rear portion of the driving-shaft 126 is a gear 128,which meshes with agear 129, mounted on a shaft 130, journaled on the rear portion of the frame, and which may be driven by means of an electric 4motor (not shown) mounted on the rear end of the frame for the fianging and driving mechanism or by any other suitable means, so as to transmit power to the driving-shaft, Mounted on the shaft 126, between the gears 125 and 128, is a gear 131, which meshes with a pinion 132, mounted on a shaft 133, which is journaled longitudinally Vwith the shaft 126 and below the same.

On the front end of the shaft 133 is mounted a beveled gear 134, which meshes with a smaller gear 135, mounted on the upper end of a shaft 136, vertically journaled below the shaft 133. On the lower end of the shaft 136 is a beveled gear 137, which meshes with beyeled gears 138 and 139, mounted on a shaft 140, transversely journaled on the lower portion of the frame. Each of the gears 138 and 139 is provided on its inner surface with a clutch-face 141 to coact with a clutch 142, which is movably mounted on the shaft 140, the position of which clutch may be shifted by means of a lever 143, suitably fulcrumed on the frame. The inner end of this lever is formed with a yoke 144 and is connected to the clutch in the ordinary manner. On each end of the shaft 140 is mounted a gear 145,

vwhich meshes with the vertically-curved rackbars 146, one of which is suitably mounted on the foundation on each side of the frame 110, as is clearly shown in Fig. 5 of the drawings. By moving the lever 143 in the proper direction it isevident that the clutch 142 will be thrown into engagement with one of the gears 138 or 139, so as to cause the shaft 140 to be rotated in the proper direction to raise or lower the frame which carries the Hanging and driving mechanism. 'Transversely journaled in suitable bearings 147 on the front part of the frame 110 and below the drivingshaft is a rock-shaft 148, on which is rigidly mounted a bracket 149, on which is transversely journaled in a suitable recess 150 a roller 151, used fol forming the flange on the disk or plate. On each end of the shaft 148 is mounted a segmental gear- 152, which meshes with similar gears 153,-rigidly mounted on another rock-shaft, 154, which has its bearings 155 in the sides of the frame. The shaft 154 is provided at one of its ends with ahandwheel 155, used for turning the same so as to adjust the roller 151 to the proper position to form the flange 123 on the disk or plate, which is done by reason of the engagement of the racks 152 and 153, as will be clearly understood by reference to the various views of the drawings.

The operation of the machine is as follows: When it is desired to dish or iiange a disk or plate, the upper frame may be raised suiiiciently to permit of the plate being inserted between the disks 83 and 108 by turning the adjusting-shafts 49 in the proper direction, or if it is desired to 'raise the upper frame higher than the shafts 49 will force it said frame may be raised by means of suitable tackle. After the plate or disk shall have been inserted between the rotatable disks 83 and 108, so as to rest on the latter, the upper frame may be lowered, when by turning the frame or screw-shafts 90 and 91 the detents or feet carried thereby will be caused to travel on said rods, so as to center the disk or plate, after which the upper frame may be screwed down farther, so as tocause the disk or plate to be firmly clamped between the rotatable disks at the center of the machine. In order to dish the plate or disk, the brackets or hangers 100, carrying' the rollers 101, may be adjusted to the proper inclination by means of the opening in the vbrace-plates 95 and bolts located therein, when by turning the shaft 58 the segmental gears 56 will be forced downwardly, thus causing the rollers 71, which are carried by said gears and which may be suitably adjusted by means of the adjusting screws or rods 64, so that said rollers will impinge the upper surface of the plate or disk, which in its heated condition will be bent downwardly onto the rollers 101, in which position it will be rotated between the rollers 71 and 101 by reason of the frictional contact of the wheels 122 and 127, which are driven as above set forth. If it is desired to form the disk or plate 74 with afiange, the rock-shaft 154 may be turned in the proper direction to cause the gears 153 thereon to force the gears 152 on the shaft 148 in the proper direction to cause the roller 151 IIO to impinge the upper surface of the edge of the disk or plate, thus forcing it downwardly over the periphery of the beveled wheel 122, in which operation the disk or plate will be upset or slightly reinforced at the bend of the flange, thus strengthening the same at the said point. In the operation of Hanging or dishing that portion of the disk near the driving- Wheels 122 and 127 will be supported by means of the rollers 115, which are carried by the frame for the Hanging and driving mechanism.
